How can you people be so cruel? Mukti was raped, in Bajaj's own house too. So, if he believes that Sharad is not the rapist, he is to an extent responsible for Mukti because it happened in his house.
Also, you may exchange insults, but hitting your wife is completely crossing the line. A wife deserves some respect. bajaj could have said stuff back, but oh no!! He had to be overly dramatic and hit her. I would love to see his expressions when he finally realizes that he was so wrong!!! That'll b worth seeing.
